REPEATING ATTACHMENT FOR PHONOGRAPHS.

SPECIFICATION forming part of Letters Patent No. 722,616, dated March10, 1903.

Application filed June 19,1902. Serial No. 112,350. (No model.)

To all whom it may concern:

Be it known that I, DAVID PETRI-PALMEDO, a citizen of the United States,residing at Scranton, in the county of Lackawanna and State ofPennsylvania, have invented new and useful Improvements in RepeatingAttachments for Phonographs, of which the following is a specification.

This invention relates to an attachment for sound recording andreproducing machines; and the object of the invention is to providesimple mechanism for easily and conveniently repeating portions, such assingle words or short sentences or a single bar or fugue of a I5recorded speech or a piece of music, respectively.

The invention in one simple and convenient embodiment thereof is shownin the accompanying drawings,forming a part of this speci- 2o fication,and in which- Figure 1 is a side elevation of certain of the parts of anEdison phonographembodyin g my improvements. Fig. 2 is a front elevationof the same.

Like characters refer to like parts in both figures of the drawings.

I have shown in the drawings a simple organization of parts for thepurpose of representing the character of the invention, and by the samein order to repeat any part of a record upon the cylinder of theinstrument the feed-screw mechanism must be temporarily disengaged, thespeaker or reproducing-diaphragm must be lifted from the record, and thereproducing-stylus set back a certain distance. The reproducingpointmust be brought in contact with the record again and the feed mechanismput in cooperative relation therewith. These functions I accomplish by asingle motion of the hand, as will be clear from the followingdescription of my attachment.

In the drawings, A represents the mandrel of an Edison phonograph; B,the wax cylinder upon which sound is recorded.

Ois the so-calledspeaker-arm, that carries the speaker,with itsdiaphragm and reproducing-point I. This speaker-arm is guided at one endon a rod D, and at the other end it to the rear endof the speaker-arm,engages a feed-screw H, which being actuated by a spring-motor causesthe speaker-arm to travel laterally across the record; but when thespeaker-arm is lifted from the ledge E the feed-screw and feed-nut G andH are disengaged, allowing the speaker-arm to be shifted back and forthon the guide-rodD independently of the feed mechanism.

All of the foregoing description pertains to the well-known apparatus ofthe Edison phonograph, and my improvements are shown incorporatedtherein.

For repeating single words, short sentences, &c., I provide'a hinge K,having wings or pieces L and L, by means of which it rides on the ledgeE of the phonograph. Two projections M and N are provided to the lowerpart of the hinge. Between these stops fits the projecting lug X of thespeaker-arm with a clearance. On the upper half of the hinge is provideda small antifriction-roller O, that rests against the circular portionof the speaker-arm, containing the reproducing-diaphragm, or theso-called speaker-ring. Ber tween the two halves of hinge K, I place asmall elastic rubber bag R, which is connected by a rubber tube Q withan elastic bulb B. On pressing the bulb R the rubber bag is inflated,the upper part of the hinge/is lifted up, and in turn lifts thespeaker-arm from the ledge E. Next by its own weight the speaker-armslides down upon the antifriction-roller O and to the left against thestop M. On releasing the pressure on the bulb R the feed mechanism isagain engaged, and the speaker-arm is again caused to ad- Vance byvirtue of the feed mechanism. The

lug is caused to travel from the projection M toward the projection L,then takes the whole hinge along with it, and at any time that arepetition of a word or sentence, 860., is desired the speaker-arm canbe set back a small distance by pressing on the bulb R in the mannerthus described, thus causing the diaphragm to repeat. The wings L and Lfrictionally hug or straddle the ledge or rail E of the frame to adegree sufficient that when the attachment is at rest and thesound-reproducing device is moved backward in the manner indicated theprojection M when engaged by the lug X will resist or stop furtherbackward motion of said sound-reproducing device.

The invention is not limited to the construction hereinbefore set forth,the same being shown and described simply for the purpose of indicatingthe nature of my improvement, for many variations in the form andarrangement of parts may be made within the scope of the accompanyingclaims. It will be also understood that the attachment is not limited inits application to any particular kind of sound recording andreproducing in- V strument.

Having described the invention, what I claim is- 1. The combination of asound-record, a sound-reproducing device cooperative therewith, feedmechanism for advancing the son nd-reproducing device, a member movablewith the sound-reproducing device and having a projection, mechanism forthrowing the sound-reproducing device out of cooperative relation withits feed mechanism, and cansing the retraction of the same until itabuts against said projection.

2. The combination of a sound-record, a sound-reproducing devicecooperative therewith, feed mechanism for advancing thesound-reproducing device, a member movable with the sound-reproducingdevice and havinga pairof projections, a lug upon the soundreproducingdevice disposed between said projections, and mechanism for throwing thesound-reproducing device out of cooperative relation with its feedmechanism, and causing the retraction of the same until'it abuts againstone of said projections.

3. The combination of a sound-record, a sound-reproducing devicecooperative therewith, feedmechanism for advancing the sound-reproducingdevice, a hinge cooperative with the sound-reproducing device and one ofthe parts of the hinge carrying an antifriction-roll adapted to engagean inclined surface upon the sound-reproducing device, and the otherpart of the hinge having a pair of projections, a lug upon thesound-reproducing device disposed between the said projections, andmeans for operating that part of the hinge which carries saidantifrictionroll, relative to the companion member of said hinge.

4. The combination of a sound-record, a sound-reproducing devicecodperative therewith, feed mechanism for advancing thesound-reproducing device, a hinge cooperative with the sound-reproducingdevice, and

one of the parts of the hinge carrying an antifriction-roller adapted toengage an inclined surface upon the sound-reproducing device and theother part of the hinge having a pair of projections, a lug upon thesound-reproducing device disposed between the said projections, aninflatable bag between the members of said hinge, and a tube connectedwith said inflatable bag, and provided with a bulb.
